CARP ET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 285,000, datedSeptember 18, 1883,

- I Application filed May 24, I883; (X model.)

To all whom, it may concern Be it known that I, MELvILLE R. BISSELL, acitizen of the United States, residing at Grand Rapids, Michigan, haveinvented new and useful Improvements in Carpet-Sweepers,

of which the following is a specification.

The presentinvention relates to that class of carpet-sweepers in which arevolving brush serves to deliver the dust or collected material intopans contained in a case or box mounted on bearing-wheels, said pansbeing arranged so that they can be. tipped for emptying them.

The object of the invention is to provide a case or box which hassupports or a supple- I 5 mentary frame at each end thereof for thereception of the bearing-wheels, so that the latter will be exposed toview and easily accessible, for the purpose of permitting dirtaccumulating on their peripheries or anything I that might clog them, tobe easily removed without the necessity of inverting the box. Anotherobject of the invention is to fit on the main frame or box and on thesupplementary end frames that support the bearing-wheels an india-rubberor elastic band, which serves as a guard for preventing themarring orinjury of furniture or other objects brought in contact with thesweeper.

The objects of my invention I accomplish .30 by the construction andarrangement of parts hereinafter described and claimed, and illustratedin the accompanying drawings, in which' v Figure 1 is a perspective viewof a sweepercasing constructed according to my invention. Fig. 2 isabottom view of the same. Fig. 3 is an end elevation with part of thesupplementary frame broken away to show the spring-supports for thebearing-Wheels.

40 The case or box A contains in its lower part two pivoted pans ordust-receivers, B, between which is arranged a revolving brush, 0,having its bearings in supplementary frames D, arranged beyond the endsof the box proper of the sweeper. These frames are formed by extendingthe side boards of the box A 'be yond the ends thereof, as is shown ata, and attaching to said extended portions at each end of the box atransverse bar or board, b, whose lower edge is on a level with thelower edge of the box A. Suitable bearing-plates or supports, D,attached to the inner sides of the transverse bars or boards I) receivethe gudgeons orjournals on the ends of the revolving brush, and thesebearing-plates are generally 5 provided with slots, so that they can bead justed up and down on retaining-screws passing through said slotted 7plates and entering the transverse bars or boards I).

The bearing or transporting wheels E, for

supporting the sweeper and actuating the revolving brush, are arrangedinpairs between the supplementary frames D and the ends of the box, andare mounted or journaled in hangers or yokes F, which are carried byspring-arms G. The bearing-wheels may have hard or solid peripheries,orbe provided with indiarubber tires, for obtaining greater adhesionbetween the bearing-wheels on the brush-shaft, and for lessening noise.

The spring-arms consist of a long plate or member, 9, to the upper endof which the wheelyoke is secured and a shorter plate or member, h,bearing'upon the inner side of the extended portion of the sweeper-box.A bolt or pin, H, 7 5 passing through an eye or contracted portion atthe j unction of members 9 and h, serves to hold the spring-arm G inposition. The bolt or pin extends through the bar or boardb, and

enters the end board of the sweeper-box. The brush shaft or spindlearranged between the wheels at each end of the box has the customarywheels, R, turning in contact with the bearing-wheels, for operating thebrush by means of said wheels. These wheels B may 8 5 have hardperipheries, or be provided with the bearing-wheels at a properelevation or plane in relation to the base of the sweeper- 5 box. Agroove made in the side boards of the sweeper-box and in thesupplementary frames D receives a continuous india-rubber or otherelastic band, K, which serves as a cushion or guard for preventinginjury to furniture and other objects brought in contact with thesweeper. This elastic band is stretched and slipped over the sweeper boxand supplementary frames, and retained in its seat or groove by its ownelasticity.

It will be evident that by extending the side boards of the sweeper-boxbeyondthe ends thereof, and attaching transverse bars to said extendedportions, supplementary wheel-supporting frames of a firm and stablenature are provided, and that the wheels arranged in said supplementaryframes are exposed to sight and are readily accessible, so that they canbe easilyfreed from accumulated dirt.

I am aware that a carpet-sweeper has heretofore been composed of asweeper-case having secured to each end a separatejournal-box supporthaving a slot receiving the box, in which the journal at one end of thebrushshaft is arranged, said journals of the brush shaft being retainedin the slotted journal-box supports by engaging with the ends of a bailto which the sweeper-handle is secured. My invention differs from suchin several material respects, in that I prolong the side pieces ofthesweeper-case itself, and connect the extremities of such side pieces bytransverse bars having bearings which of themselvessupport and hold theend journal of the brush-shaft when the sweeper-box is lifted; and,further, the transverse connecting -bars have their lower edges on alevel with the bottom of the sweeper-box, thus bringing such bars in thesame proximity to the floor as the box itself. I am alsoaware that acarpet-sweeper has been provided with a continuous elastic band arrangedin a groove formed in the side and end walls of the sweeper-box, andsuch therefore I do not claim.

Having thus described my invention, what I claim is i 1. In acarpetsweeper, the combination of the box having its sides extendedbeyond its ends, and the transverse bars for connecting said extendedportions with the bearing wheels arranged between the ends of the boxand said transverse bars, and the revolving brush having itsend journalsupported by bearings on the transverse bars, such bearings retainingthe brush-shaft in position when the sweeper case is lifted,substantially as described.

2. In a carpet-sweeper, the combination, of the sweeper-box having itsside pieces pro longed beyond its ends, the transverse bars connectingthe extremities of the side pieces, the brush-shaft having the journalsat its ends supported by bearings on the transverse bars, and thebearing-wheels arranged between the ends of the box and the transversebars, substantially as described.

3. I11 a carpet-sweeper, the combination of the sweeper-box having itsside pieces prolonged beyond its ends, the transverse bars connectingthe extremities of the side pieces and having their lower edges arrangedon a level with the bottom of the sweeper-box, and the brushshaft havingend journals supported by bearings on the transverse bars, substantiallyas described.

4. A carpet-sweeper composed of a sweeper box having its side piecesprolonged beyond its ends and connected at their extremities bytransverse bars which have bearings to support the journals on the endsof the brushsh aft, said side pieces and transverse bars having groovesin which is arranged an elastic band, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.
